writes in with a story about how important buying the right kind of kitty litter can be. "In February, a 55-gallon drum of radioactive waste burst open inside America's only nuclear dump, in New Mexico. Now investigators believe the cause may have been a pet store purchase gone bad. 'It was the wrong kitty litter,' says , a geochemist in Richland, Wash., who has spent decades in the nuclear waste business. It turns out there's more to cat litter than you think. It can soak up urine, but it's just as good at absorbing radioactive material. 'It actually works well both in the home litter box as well as the radiochemistry laboratory,' says Conca, who is not directly involved in the current investigation. Cat litter has been used for years to dispose of nuclear waste. Dump it into a drum of sludge and it will stabilize volatile radioactive chemicals. The litter prevents it from reacting with the environment. And this is what contractors were doing as they packed Cold War-era waste for shipment to the dump. But at some point, they decided to make a switch, from clay to organic. 'Now that might sound nice, you're trying to be green and all that, but the organic kitty litters are organic,' says Conca. Organic litter is made of plant material, which is full of chemical compounds that can react with the nuclear waste. 'They actually are just fuel, and so they're the wrong thing to add,' he says. Investigators now believe the litter and waste caused the drum to slowly heat up 'sort of like a slow burn charcoal briquette instead of an actual bomb.' After it arrived at the dump, it burst."Read Replies (0)

writes "The only negative thing to say about Hacking Point of Sale: Payment Application Secrets, Threats, and Solutions is its title. A cursory look at it may lead the reader that this is a book for a script kiddie, when it is in fact a necessary read for anyone involved with payment systems. The book provides a wealth of information that is completely pragmatic and actionable. The problem is, as the book notes in many places, that one is constantly patching a system that is inherently flawed and broken."

It wasn't long after the rise of the Oculus Rift that Sony hopped on the virtual reality bandwagon and announced a headset
of their own. Now, Eurogamer has had a chance to operate and test Sony's hardware
, which they say "has its own distinct vision for VR," as well as a distinct focus on console gaming."On the 640x768 per eye first-gen Rift, the result was the perception of a disappointingly minuscule resolution, with a highly distracting "screen door" effect where you could see between the pixels. This is far less of an issue with Morpheus, and we were pleasantly surprised by how good image quality is in an environment where resolution remains at a premium. In discussing the situation with Sony, it's clear that some effort has gone into judging how to best apply the fisheye lens effect that distorts the image, with a stronger focus on retaining resolution in the key focus area. Over and above that, we wouldn't be surprised if the narrower field of view also contributes to improving image integrity. ... However, in comparing Morpheus to what we've seen from Oculus VR, it's perhaps surprising to discover that a truly transformative element of the proposition comes from a piece of hardware that you might already own: PlayStation Move. Our aspirations for the hardware were never fully realized, but the hook-up with Morpheus is a match made in heaven - in fact, if there is to be a struggle for market leadership with Oculus (and potentially Microsoft), the existing motion controller is undoubtedly one of the strongest weapons in Sony's arsenal."Read Replies (0)

An article at Wired takes a look at two multiplayer survival games, DayZ
, and at the behavior of players when their actions are freed from a civilized moral code
. 'Violence wouldn't bother a psychopath, [Dr. Adam Perkins] says, but they might have another incentive to avoid violence: the consequences of getting caught. Most psychopaths are logical people, he says, and understand that actions bring consequences. The threat of repercussions — say, for example, prison — might keep them from acting out. Such disincentives do not exist in virtual worlds. Absent a sense of empathy, you're free to rob and kill at will. What we do with this reveals something about us.
Jon Ronson, author of The Psychopath Test
, says imagining ourselves doing something horrible is a way to see ourselves in a new light. "One of the ways we keep ourselves moral is to imagine the terrible things we could do, but then don't do," Ronson says. "You stand on a train platform and think, 'I could push that person in front of the train.' That thought pops into your head, and it doesn't make you a lunatic. It makes you a good person, because what you're actually saying is, 'Oh my god, I’m capable of doing a terrible thing, but I would never actually do it.'" ... But we're still left with the big question: Are our actions in a virtual world tantamount to imagining those things we could do in real life but never would? Or are we merely behaving as we would in real life if there were no consequences for our actions?'Read Replies (0)

This analysis of trading logs
from the Mt. Gox Bitcoin exchange analyzes a subset of the transactions that took there prior to the Mt. Gox collapse
, and makes the case that two bots (the writer calls them "Willy," and "Markus") were making suspicious transactions which may have been used to intentionally manipulate the trading price, and which can explain the loss of Bitcoin inventory on which the exchange's failure was blamed.
The author of the analysis says "[T]here is more than plenty of evidence to suspect that what happened at Mt. Gox may have been an inside job. What I hope to achieve by releasing this analysis into the wild is for the public to learn the truth behind what happened at Mt. Gox, how it affected the Bitcoin price, and hopefully for the individuals responsible for the massive fraud that occurred at Mt. Gox to be put to justice. Although the evidence shown in this report is far from conclusive, it can hopefully spur a more rigorous investigation into Mt. Gox’s accounting data, both by the public (using the leaked data) and the authorities (forensic investigation on the actual data)."Read Replies (0)

That smoking is bad for your health is a commonplace; cancer, lung disease, and other possible consequences can all shorten smokers' lifespans. A new meta study from researchers at Oxford concludes that mental illness is just as big a factor in shortening lives
, and not only because depression is a contributing factor to suicide.
From the story at NPR: "We know that smoking boosts the risk of cancer and heart disease, says Dr. Seena Fazel, a psychiatrist at Oxford University who led the study. But aside from the obvious fact that people with mental illnesses are more likely to commit suicide, it's not clear how mental disorders could be causing early deaths. The researchers looked at data on 1.7 million patients, drawing from 20 recent scientific reviews and studies from mostly wealthy countries. Comparing the effects of mental illness and smoking helps put the stats in context, Fazel tells Shots. 'It was useful to benchmark against something that has a very high mortality rate.'"
